Answer 2

Answer:

18 is A

19 is B

20 is B

Step-by-step explanation:

18 is A because the endocrine system is basically the only system that sends chemicals, mainly hormones throughout the body, and the nercous system is the only system that acts like wiring because of the nerves

19 is B because the nervous system needs the brain to function, the nerves send signals to the brain, and the brain sends signals back through the brain stem

20 is B because it can't be A, since that is multiple tissues and organs, it can't be C because cells are what make up tissues, and it can't be D since organ systems require organs not just tissues

hope this helped :)

A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20

b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

Square Area

8-3 to get the right side of the square which equals 5. So the square is 5*6=30

Triangle Area

To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5

but you have 2 triangles so multiply 4.5*2 and that's 9.

So, 30+9=39

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) − 150°. Find m∠Y.

Answers

Answer:

∠s + ∠y are complementary

∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90

4y - 100 + y = 90

5y = 90 + 100

5y = 190

y = 38

Ans: y = 38°

Step-by-step explanation:

Number of diagonals in a 88-gon = 3740

Step-by-step explanation:

Number of diagonals of a polygon

(where 'n' is the number of sides)

[tex] = \frac{n \times (n - 3)}{2} [/tex]

[tex] = \frac{88 \times (88 - 3)}{2} [/tex]

[tex] = \frac{88 \times (85)}{2} [/tex]

[tex] = \frac{7480}{2} [/tex]

explain how to find the slope of a line through two points on a table

Answers

Answer:

you use slope formula m=y2-y1/x2-x1

m=21-11/5-3=15.8

Step-by-step explanation:

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1

5 is x2 11 is y2

m=y2-y1/x2-x1

m=21-11/5-3=15.8

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62

Answers

pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)

Answer:

2(4 w + 3) = 62

width =7 length = 21

Step-by-step explanation:

For the perimeter you need :

2 times the width and 2 times the length (length =3w)

2(w+1) + 2 (3w+2) =

2w+2 + 6w+4 =

8w +6

you can factor this by:

2(4w+3)

8w +6= 62

8W = 56

w= 7 l= 21

2(7+1) + 2 (21+2)

16 + 46 = 62

Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.

Answers

Answer:

Inequality: .80x +21 ≤ 82

Answer: 76.25 miles in total

Step-by-step explanation:

Hi,

An inequality to represent this is .80x +21 ≤ 82

(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).

Now we solve...

.80x + 21 ≤ 82

Subtract 21 on both sides...

.80x ≤ 61

Now, divide by .80 on both sides...

x ≤ 76.25

He can drive up to 76.25 miles in total

Hope this helps :)
